Title: Battery charging circuit
Inventor: TANBACHI AKIRA
IPC: H02J7/10
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To make a signal line for control unnecessary by providing a means which limits charging when either one of first and second control sections satisfy preset conditions, and at the same time, transmitting the information on the limiting state to the other control section depending upon the magnitude of the charging current received through an electrode section. SOLUTION: When a commercial AC voltage is supplied to an adapter 20 (first control section) for charging in a state, where the main body 17 (second control section) of an electric appliance is connected to the adapter 20 through an electrode section 15, an inverter circuit 16 starts to output a charging voltage. When the circuit 16 starts to output the charging voltage, an output control circuit 23 supplies a charging current upon which no output voltage limitation is placed with respect to the main body 17 from the adapter 20. On the main body 17 side, a charging timing control circuit 27 discriminates that the time for charging is reached and charges a secondary battery. A timer circuit 24 measures the charging time, and when preset charging time has elapsed, limits the output of the inverter circuit 16 by sending an output control signal 32 to the output control circuit 23.

Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To efficiently decompose TOC and to produce highly pure ultrapure water by adjusting the pH of the water to be injected with ozone in a specified range when the extrapure water is produced by irradiating it with U.V. rays together with injection of ozone into water and decomposing the TOC. SOLUTION: The TOC is decomposed by injecting ozone into water and irradiating it with U.V. rays to produce the ultrapure water. In this case, the pH of the water injected with ozone is adjusted at 3.5-6. On the other hand, an extrapure water manufacturing device is composed of a pretreatment device 1, a primary pure water manufacturing device 2 and a secondary pure water manufacturing device 3. The primary pure water manufacturing device 2 is arranged at least with a decarboxylation tower and an ozone absorption tower. In this case, acid is injected into the decarboxylation tower and the pH of the water introduced into the ozone absorption tower is adjusted at 3.5-5. Thus, the TOC is efficiently decomposed and highly pure ultrapure water is produced.

Title: Ink jet recorder
Inventor: SUGA MICHIHISA
IPC: B41J2/015
Filed: 1987-07-30
Abstract: PURPOSE:To contrive a high-speed printing action, by a recording method wherein, a drive means is excited according to an input electric signal while the relative position of a film to a recording needle is changed, and an ink in through holes is injected toward a recording paper. CONSTITUTION:A film 102 travels in a direction of an arrow 109 relative to a guide member 106 and a recording needle 103. When the recording needle 103 is displaced in the direction of an arrow 110 due to the action of a drive means, an ink in a guide is pressurized to extrude an ink staying in through holes outside. The excitation of the drive means is completed in a short time and the recording needle is returned to an initial position. As a result, the ink is pulled into the guide, and the through holes after the ink was jetted out become empty. The film 102 travels with time so that through holes filled with an ink are disposed on the guide hole to again establish an initial state. The refilling of an ink is realized by the traveling of the film 102 relative to the guide member 106 and the recording needle 103. In this manner, an ink with every viscosity is made available, and a high-speed recording can be realized.
